Optimizations are just a start, there were other suggestions here.

What exact optimizations have you done? There are multiple lists. You got all the bios ones done? Cstate? Tried hyperthreading off ? All networking disabled? Bluetooth disabled?

and basic troubleshooting... make sure ignore errors is not checked... can you get Pro Tools to throw an error... what exact one? That would be making a lot of progress to know.

Then move all .aaxplugin files out of their folder, trash prefs and restart Pro Tools. With just the base plugins installed (that Pro Tools magically puts back) does this behave better... I don’t care if you were not using those other plugins get them all fully removed and test.
